Lubrication system for pump drive

A booster pump system, comprising:

• a cylinder comprising a chamber;
• a piston disposed within the chamber of the cylinder;
• an electric motor configured to drive movement of the piston relative to the chamber of the cylinder to pressurize fluid within the chamber and discharge pressurized fluid from the chamber, wherein the electric motor is disposed in a housing;
• a lubricant reservoir;
• a conduit fluidly coupled to the lubricant reservoir and configured to direct lubricant from the lubricant reservoir into the housing;
• and
• a sensor configured to monitor a level of lubricant in the lubricant reservoir.

A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, are configured to cause the one or more processors to perform operations comprising:

• monitoring a level of lubricant contained within a lubricant reservoir, wherein the lubricant reservoir is configured to store lubricant and to direct lubricant into a housing containing a motor of a booster pump, the motor being configured to drive movement of a piston of the booster pump to pressurize fluid within a cylinder of the booster pump;
• determining the level of lubricant in the lubricant reservoir is below a threshold level;
• and
• reducing operation of the motor in response to determining the level of lubricant in the lubricant reservoir is below the threshold level.
